curved tube
Bent hollow cylinder
A curved tube is a hollow cylindrical structure that bends rather than running straight.
The term appears in technical contexts—plumbing, medical devices, laboratory equipment—where the shape matters for function: The curved tube directs exhaust away from the engine.
A bent pipe or elbow joint serves the same purpose.
